Issue Description
The GRANBOARD and LED Mat does not sync (colors do not change)
Connection issue between the dartboard and the app.
Possible Causes
Insufficient power supply
USB cable you use does not support data transmission
Using both AA batteries and USB charger simultaneously
LED MAT setting in the GranBoard app is turned off
Solutions
Check USB Charger Amperage
Required Power
LED MAT: 2.4A or higher
GRANBOARD: 1.5A or higher (2.4A recommended)
Common Error
Are you using a Dual-Port USB?
Dual-port USB charger with 2.4A maximum output may only supply 1.2A per port when both ports are in use. This causes insufficient power and LED malfunction.
Use a Data-Transfer USB Cable
Changing LED color is controlled by the app.
It is required to transfer signals:
App → GRANBOARD → LED MAT PC BOX → LED MAT
If you're using a charge-only cable, the LED effects will not sync.
Always use the USB cable that came with the product.
Remove AA Batteries
Make sure you are not using batteries.
To enjoy the LED effects, please use a USB power source.
